SPREADER FOR HARROWS.

SPECIFICATION forming part of Letters Patent No. 488,352, dated December 20, 1892.

l Application filed April 15, 1892. Serial No. 429.259. (No model.)

To @ZZ whom it may concern:

Be it known that I, Louis C. EVANS, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Spreaders for Harrows, of which the following is a specification.

My invention relates to improvements in harrows, and it especially relates to novel means of forming harrows of different widths by uniting two or more harrow sections.

The object of my invention is to provide novel means for uniting harrow sections in such a manner that the harrow sections so united shall be spread apart at suitable distances,to form practically one harrow, havingthe combined capacity of the united sections.

My invention consists in the various constructions and combinations of parts hereinafter described and pointed out in the claims.

In the accompanying drawings Figure lis a plan view of a device embodying my invention, showing the method of forming a two section barrow or a four section harrow, part of the connections for the four section harrow being illustrated indotted lines. Fig. 2 is a plan view of the same converted for use as a three section harrow. Figs. 3 and-i are detail views of the connecting bars forming the spreader. Figs. 5 and 6 are detail views of the adjustable connecting devices, used in connection with the said bars.

Like parts are represented by similar letters of reference in the several views.

In the said drawings A, A', A2, A3, represent harrow sections which may be of any desired construction, each section being a du plicate of the other section. Each of the sections are provided with suitable loops or hooks a, to which the hitching devices may be attached.

B, B andO, represent respectively the connecting bars, which are used to join the said sections and which are so constructed as to be adapted for use to form a harrow of any desired Tsize within certain limits, by simply uniting two or more harrow sections together, in the manner hereinafter more fully specied. The connecting bars B and B', are duplicates one of the other and are each provided with openings b b, into which are secured eye-bolts h', at suitable distances apart to correspond with the connection a., on the harrow sections, suitable connecting rings or clevises h2, being employed for joining the eye-bolts to said connections and thus connect two harrow sections together, as shown in Fig. l. Each of the bars B and B', is provided with an additinal opening h3, adapted to receive an eye-bolt b4, arranged on the opposite side of said bar from the eye-bolt h'. The bars B, B', are further provided with an adj ustable connecting loop or clevis b5, adapted to be arranged either at the middle of the bar, as shown at the right of Fig. 1, or near one end thereof and opposed to the connecting bolt b4, as shown at the left of Fig. l. The bar C, is also perforated with openings o, adapted to receive an eye-bolt c' having connecting rings c2. These eye-bolts are arranged in pairs, three pairs in all being used, each pair being adapted to coincide with and be connected to the hitch connection a, of a harrow section, and thus furnish the means for joining three sections, as shown in Fig. 2. The bar C, is alsofurther provided with hitching clevises c3, which are the same as those h5, on the bars B and B', the preferable form of these hitching clevises being illustrated in Fig. 6 and consisting of a U-shaped bolt e, screw-threaded at each end and provided with connecting bars e' e2, threaded onto the ends of said U-shaped bolt e, which is provided with nuts e3,by means of which the said clevis may be clamped to the connecting bars B' and O, said bars being adapted to be inserted between the respective sides of the U-shaped bolt e, and the cross bars e' e2.

When in use with a four section harrow the connecting bolts c' are placed in the outer openings and middle openings, respectively, of the bar O. The respective hitching clevises b5, are arranged on the bars B and B', so as to stand opposite the respective bitching connections o', of the bar C, at each end thereof, as shown at the left of Fig. l, and in dlotted lines at the right thereof. If a two section harrow is desired, one of the bars B, is disconnected from the har O, and the connecting clevis b5, moved to the center of said bar to form the hitch. If a three section harrow is desired, one of the bars B, is connected at its outer extremities, through the medium of the IOO connection b b', to the bitching clevises c3. Connecting eye-bo1ts c', are inserted in tbe Vacant openings c, in said bar, thus adapting the said bar to three sections, as shown in Fig. 2. f f

It will be seen bythe arrangement described that the bitching points of the shorter connecting bars correspond with the connecting points of the longer bars. At tbe same time the bitching points of the longer bar coincide with the bitching points of the shorter bar, so that either bar may become the bitching bar and the other bar the connecting bar, thus furnishing tbe means for providing a two, three or four section barrow by simply adjusting and re-arranging the parts.

Having thus described my invention, I claim:-

1. The combination with two or more barrow sections, of a main bitching bar and two or more intermediate connecting bars, each of said intermediate bars and said main bar having lateral openings to receive eye-bolts corresponding to tbe bitching connections of said barrow sections, each of said bars being further provided on the opposite side with bitching connections which correspond tothe eye-bolts in the other bars, one of said bitching connections in each bar being detachable, substantially as and for the-purpose specified.

2. The combination with two or more harrow sections, of a main bitching bar, and one or more intermediate connecting bars, each of said bars being provided with lateral openings adapted to receive eye-bolts corresponding to the bitching points of said barrow sections, said bars being each further provided on the opposite side with bitching connections which correspond to the connecting eye-bolts of the other bar, one of said bitching connections having a permanently secured eye-bolt and the other a detachable connection, consisting of a U-sbaped connecting loop, clamping plates and adjusting nuts, substantially as specified.

In testimony whereof I have hereunto set my hand this 11th day of April, A. D. 1892.

LOUIS C. EVANS.
